Detailed Description

A constraint.

Constructor & Destructor Documentation

constraint() [1/2]

tetengo::lattice::constraint::constraint

(

)

Creates an empty constraint.

It matches any path.

constraint() [2/2]

tetengo::lattice::constraint::constraint ( std::vector< std::unique_ptr< constraint_element > > &&  pattern )

explicit

Creates a constraint.

Parameters

pattern

A pattern.

Member Function Documentation

matches()

bool tetengo::lattice::constraint::matches

(

const std::vector< node > &

reverse_path

)

const

Returns true when the path matches the pattern.

Parameters

reverse_path

A path in reverse order.

Return values

true	When the path matches the pattern.
false	Otherwise.

matches_tail()

bool tetengo::lattice::constraint::matches_tail

(

const std::vector< node > &

reverse_tail_path

)

const

Returns true when the tail path matches the tail of the pattern.

Parameters

reverse_tail_path

A tail path in reverse order.

Return values

true	When the tail path matches the tail of the pattern.
false	Otherwise.
